摘要：A touch screen (1111) having an active surface area (1112) which extends in threephysical dimensions (x-, y- and z-dimensions) is provided. In the figure the active surfacearea has a U-shaped form. When a user slides his finger over the active surface area thetactile feedback gives him information about the position of the finger. The touch screenis activated when the active surface area senses a certain pressure from the finger. Theuse of the touch screen is facilitated especially when the user is on the move or when thetouch screen is out of sight. Such use is common when operating hand-held terminals.
